Our Glou Glou is a brand new Overdrive in the GUP Tech catalogue.
It's a 4558 based boost-overdrive pedal inspired by the Blue Note and the Animal pedals by J Rockett. Classic Vol-Gain-Tone structure with a Fat knob to add or cut bass to your signal. The Hot toggle add quite a huge amount (in low position) of gain to your tone if you want to turn it into a Marshall-In-A-Box.
Start with volume at max, and gain at noon. Tone is acting like a high-cut, so put it at 0 at first and remove as much treble as you want while turning clockwise. The sweet spot is at 2-3. The FAT knob add a lot of bass to the tone as you turn it up.
Design note : Glou Glou is the classic French way to imitate the Turkey sound, that's where the inspiration came from :)
